JAMES W. SMITH, 'OF ROME, GEORGIA.

COTTON-SEED CLEANER AND s EPARAToR.

sPEcIFIcA'rIoN forming part of Letters Patent No. 518,124, dated April 10,1894.

i Application filed August 3, .1893. Serial No. 482,279. (No model.)

To all whom it may concern:

Be it known that I, JAMES W. SMITH, residing at Rome, in the county of Floyd and State of Georgia, have invented certain new and useful Improvements in Cotton-Seed Cleaners and Separators, of which the following is a specification.

My invention has for its object to provide a cotton seed cleaner and separating machine, which will effectively serve to clean the seed, and separate therefrom nails, gravel, iron ore and the like, and such invention consists inV the peculiar combination and novel arrangement of parts, all of which will hereinafter be iirst described and then particularly pointed out in the claims, reference being had to the accompanying drawings, in which* Figure 1 is a perspective view of my improved machine, partsl being broken away and Fig. 2 is a vertical longitudinal section of the same on the line 2-2 Fig. 1. Fig'. 3 is a detail view.

Referring to the accompanying drawings A,

` indicates the main frame or casing, formed at one side into a receiving compartment B, and at the other with a discharging chamber C.

At the top and over the front edge of the receiving compartment B, is disposed the mouth or receiving hopper D which has an inclined bottom E, and discharges into one end of compartment C, onto its inclined bottom CX, the lower end of which terminates at a discharge opening F, through which the cleaned seed is discharged, as will presently appear. It will be noticed by reference to Fig. 2, that the lower end of the incline bottom E, stops short of the upper end of a reversely inclined chute or board G, the upper edge of which has a transverse plate H, the upper edge of which extends above the upper face of the board as at h and formsa guard or retarding strip for a purpose hereinafter stated. It will also be noticed that the plate H, inclines in a plane parallel with the bottom E, and between such board Gand the end d of the bottom is formed a passage or outlet I. The lower end of chute Gdischarges over an opening J, at the bottom' of a blast chamber K with which connects at k a blast device of any well known construction, and to provide for an adj ustmentof the blast, I provide Ya simple valve mechanism which consists of a slide plate L held to slide on ways Z, its rear end having a hand hold Z',

while its front end has a hinged cut olf valve member M, which in turn is connected by a hinged member N with the bottom E as clearly shown in Fig. 2.

O indicates a drawer disposed under the opening J.

So fan as described, it will be noticed, that as the seed is fed into-the hopper, and passes down the inclined bottom E the heavy particles will drop through the opening I, while the seed will be blown by the blast over the guard plate onto the inclined bottom CX in chamber C, and passesout through the opening F at the bottom. The larger. or heavy particles as they fall through the opening slide down theinclined boardG and pass out through openings P, and J and drop into drawer O. It will be also readily seen that by providing a guard plate at the upper end of board G, such of the light foreign particles as would be blown upward by the blast, will be retarded by such guard plate and held from passing into the seed receiving compartment, and by providing an adjustable valve M arranged as shown and described, the size of the opening P and force of the blast can be regulated, by means of the slide member L.

- To provide for increasing or decreasing the retarding power of board G, the plate H may be adjustably secured thereon; I prefer however, to arrange such board for longitudinal adjustment in the guides g, and for such purpose a diagonal slot g2, is formed in one of the side walls a, through which passes a stud g3, on which is litted'a set screw g4, which screw also forms a convenient finger piece whereby to move the board to the position desired. If desired the board G, may also be formed with a diagonally arranged groove G3, in the boti tom of which are apertures as at g5; additional openings gG being also provided to the front of which are arranged deflector members 97; such members, openings Q6 and g5 and the groove, serving to form eddies in the blast as it passes up the board G, and prevent the full power thereof operating against the heavier IOC Having thus described my invention, what I claim, and desire to secure by Letters Pat-V its lower end can be set to adjust the lower opening of such blast way, all arranged substantially as described and shown.

2. In a machine for the purpose described, the combination with the seed receiving chamber, and the inclined hopper discharging therein, and a blast chamber, of an open way inclined reversely to the hopper, and opening through it in its discharge end, said way having a longitudinally adjustable bottom, having a retarding strip at its upper end, and a top member adjustably connected, whereby its lower end can be raised or lowered, means for setting such member, adapted to be oper-4 described, the combination with the inclined hopper bottom, the chamber C having an inclined bottom C and exit F, and the opening I between the hopper bottom and the mouth of chamber C, of the rearwardly inclined board G, having its upper end provided with a retarding plate, and projected into the opening I, of a blast chamber, a waste receiving box under such chamber, and a cut off slide between such chamber and waste box al1 arranged substantially as shown and described.

4. The combination with the hopper, the seed receiving', chamber, the opening I and the blast devices, including the valve M, of the inclined board G having a retarding strip I-I at its upper end fitting in the opening I, and provided with an angular groove in its upper face, all substantially as shown and described.
